Design outcomes

Primary

MeasureTime frame
Main Objective: The overall objective of the study is to evaluate the clinical safety and potential efficacy of favipiravir relative to the control arm in patients hospitalized with COVID-19;Secondary Objective: The overall objective of the study is to evaluate the clinical safety and potential efficacy of favipiravir relative to the control arm in patients hospitalized with COVID-19;Primary end point(s): Time to clinical improvement measured as improvement for = two categories on a 7-point ordinal scale (Time frame: up to 28 days): 1. Not hospitalized, no limitations on activities 2. Not hospitalized, limitation on activities; 3. Hospitalized, not requiring supplemental oxygen; 4. Hospitalized, requiring supplemental oxygen; 5. Hospitalized, on non-invasive ventilation or high flow oxygen devices; 6. Hospitalized, on invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO); 7. Death.;Timepoint(s) of evaluation of this end point: Time frame: up to 28 days

Secondary

MeasureTime frame
Secondary end point(s): 1.Clinical Severity 1)Ordinal scale: ? Subject clinical status on an ordinal scale at days 3, 5, 8, 11, and 28 ? Mean change in the ranking on an ordinal scale from baseline to days 3, 5, 8, 11 and 28 2)National Early Warning Score (NEWS): ? The time to discharge or to a NEWS of = 2 and maintained for 24 hours, whichever occurs first. ? Change from baseline to days 3, 5, 8, 11 and 28 in NEWS 3)Oxygenation: ? Oxygenation free days in the first 28 days (if the patient is still hospitalized) or up to hospital discharge ? Incidence and duration of new oxygen use during the trial. 4)Mechanical Ventilation: ? Ventilator free days in the first 28 days (if the patient is still hospitalized) or up to hospital discharge. ? Incidence and duration of new mechanical ventilation use during the trial. 5)Hospitalization ? Duration of hospitalization (days). 6)Mortality up to 28 days;Timepoint(s) of evaluation of this end point: Time frame: up to 28 days
